- Glycolic acid is a powerful exfoliating agent.
- It can brighten and smooth skin, fade sun spots, ease congestion, and soften fine lines.
- Products containing glycolic acid include peels, toners and pads, each with their own purposes and benefits.
- For more serious skin concerns such as severe acne scarring, a chemical peel may offer superior results.
What Is Glycolic Acid?
Glycolic acid is a natural, alpha hydroxy acid (AHA) derived from sugar cane.
Alpha hydroxy acids are used for exfoliation, sloughing the upper layer from the skin to reveal brighter, fresher skin underneath.
Glycolic acid is the most common alpha hydroxy acid peel because it has the smallest molecular weight, allowing it to penetrate the skin more easily.
Glycolic Acid Peel vs. Chemical Peel
Glycolic acid peels penetrate the most superficial layer of the skin to effectively improve the appearance of blemishes, brighten skin, fade sunspots, and help soften fine lines and wrinkles. Effective results can be achieved cumulatively, with regular use over time. Glycolic acid peels require minimal downtime, and can be performed at home.
Chemical peels penetrate the skin to a medium or deep layer, injuring the skin to stimulate new growth. Medium peels generally use trichloroacetic acid, while the deepest peels use phenol.
Chemical peels target more prominent wrinkles, pigmentation irregularities and scars. The skin may take several weeks to recover, and sun exposure must be limited for several months to protect the new skin cells.
Unlike glycolic acid peels, chemical peels must be performed in an office by a dermatologist or cosmetic surgeon.
While the process is more demanding, reviews for chemical peels are generally positive.

Benefits of a Glycolic Acid Peel Facial
Glycolic peels have keratolytic properties, encouraging the separation of the tough outer layer of the skin. They can:
- Improve skin texture
- Reduce the appearance of pores
- Reduce the appearance of acne
- Improve the appearance of sunspots
- Brighten and lighten skin
The intensity of a glycolic peel can also be adjusted according to the concentration of the acid and quantity applied to the skin.

Glycolic Peel for Acne
Glycolic acid is a powerful treatment for those with acne. Oily or pimple-prone skin often has slower rates of natural exfoliation, rendering it prone to clogged pores that ultimately result in acne, blackheads or whiteheads. Glycolic acid peels accelerate exfoliation, helping to sweep away the dead skin cells and dirt that contribute to acne.
Glycolic Acid Aftercare
Products containing glycolic acid can sometimes cause short-term tingling or sensitivity. Some products may also cause the skin to feel dry: applying a nourishing moisturizer or serum following use can help alleviate any tightness or dryness.
It is essential that you apply a broad-spectrum sunscreen after applying glycolic acid, as new skin cells are particularly vulnerable to sun damage.
Takeaway
Glycolic acid represents an effective, natural method of sloughing off old skin cells to reveal a youthful, more radiant layer of skin. Based on your preference, glycolic acid can be integrated into your skincare regime as a skin peel, toner or exfoliating pad.
Regular use of glycolic acid will provide an improvement in issues such as fine lines, wrinkles and dull skin, and reduce blackheads, acne, hyperpigmentation and scarring.
